The simulation toolkit GEANT4 has been used to create high-level tools for specific user groups, such as SPENVIS in space physics and GATE in medical imaging. In Accelerator Physics, comparable efforts are being devoted to develop general-purpose programs for simulating beam lines and accelerators, allowing access to Geant4’s facilities for 3D geometry, tracking, and interactions in matter with...

We study the spatial distributions of β-activity produced by therapeutic beams of He and C ions in various tissue-like materials. The calculations were performed within a Monte Carlo model for Heavy-Ion Therapy (MCHIT) based on the GEANT4 toolkit. The contributions from positronemitting nuclei with T1/2 > 10 s, namely 10,11C, N, 14,15O, 17,18F and P, were calculated and compared with experiment...

GEANT4 is a toolkit for simulating the passage of particles though matter, which contains a complete range of functionality including tracking, geometry, physics models, and hits. In this article, an attempt to use GEANT4 Monte Carlo code to watch a double-gap Resistive Plate Chamber's (RPC) response to neutrons is presented. The simulation calculations of the double-gap RPC have been evaluated...

G4CMP simulates phonon and charge transport in cryogenic semiconductor crystals using the Geant4 toolkit. The code is capable of simulating propagation acoustic phonons as well electron hole carriers. Processes for anisotropic propagation, oblique charge-carrier emission by accelerated carriers are included. simulation reproduces theoretical predictions experimental observations such caustics, ...

This paper demonstrates the impact of pre-chemical stage, especially dissociation scheme and associated probabilities, on water radiolysis simulation using Geant4-DNA Monte Carlo track structure toolkit. The models parameters provided by TRACs have been collected implemented into Geant4-DNA. In order to evaluate their influence simulation, radiochemical yields (G-values) are evaluated as a func...

The GATE Monte Carlo simulation platform based on the GEANT4 toolkit has come into widespread use for simulating positron emission tomography (PET) and single photon emission computed tomography (SPECT) imaging devices. Here, we explore its use for calculating electron dose distributions in water. Mono-energetic electron dose point kernels and pencil beam kernels in water are calculated for dif...

Dose distribution evaluation in oncological radiotherapy treatments is an outstanding problem that requires sophisticated computing technologies to optimize the clinical results (i.e. increase the dose to the tumour and reduce the dose to the healthy tissues). Nowdays, dose calculation algorithms based on the Monte Carlo method are generally regarded as the most accurate tools for radiotherapy....
